Fig. 1. In the latter-figurefoursuch'brackets are shown as having beenv secured together,the-horizontal surfaces of the several brackets thus constituting a`figure 'of generally :square outline. rThe composite .structure vthusformed is -nows yarranged 1in' ,the a slots 3, i4 at :the up-pe'rend :ofthe column', the contacting vertical ywalls ofadj acent brackets being:seated within the 'radially extending slots. The'cap'thus formedmay ifdesired 'be used withoutfurther modification, but 'it is preferredtosecure to the horizontal supporting surfaces of the bracket members laplate such as-26, which extendsover the several brackets, and forms.the-immediate As shown in Fig. 1 this plate may be square and of a sizeto overlap and cover support for the beam or gardera'I the recesses v20vif such be formed in the outercorners of the several brackets. jThe capthus constructed is symmetrical with respect to the axis of the columnand is well adapted for supporting the ends of four beams or girders, orfor supporting a single continuous girdery extending transversely acrossit, and the ends of two abutting girders.

In the arrangement shown in Figs. 3 and 4 a pair of the three walledbrackets such ,as hereinbefore described are connected together by therivets 25j, the'connected vertical' walls 18, 17 of such brackets beingvseated-vv/*ithin a radial slot in the topl of the column. ,'Inthiscase,however, instead of connecting a second pair of similar brackets to thefirst named pair of brackets, an angle iron comprising the verticalflange 27 isjsecured tothe flanges 17, 18a of the 'axis of the post andis adapted to support ,the ends of three beams or girders abutting atthe axis of the post or a single continuous -girder having the end of abeam abut-ting one side thereof. If desired this type of column cap mayalso be provided with a :supporting plate 30 resting upon the Awalls'14: andthe flange 29. f .":In the form of deviceshown in Fig. 5 acolumn ycap is formed substantially as shown .in .Fig f 3 `comprisingthe -three walled .brackets having the vertical walls 17, 1S securedtogether by rivets such as 31 and the amalis-,17 ;and1"8a being rivetedtoi-thc .depending flange 32 of an angle iron ha'ng the .horizontalflange .33.

In this case the flange .37is' unsymmetrical -with respect to thf :memberf36, l' and vassociatedwith the longe] portion thereof is a T iron comprising th web 38 andthecross bar 39, the latter be ing connected' by means of .rivets 40 to tlrfla-nge '36. The member 38 thus serves t support the unsymmetricaloverhanging portion of the T iron whereby to strengthei .that portion ofthe .capl upon which th greater part of the weight will rest. Supporting plates 41 and 42 respective-ly ma] be associated with the capsshown in Figs 5 and 6, Z and 8 respectively if desired.

' avi-ng thus described the invention, to

gether with the mode of use thereof, what I claim and desire to secureby Letters Patent of the United States is:

l. A column cap comprising a plurality of three walled brackets 'formedfrom structural iron and arranged with one Wall of each bracket incontact with a Wall of the other, and With the third Wall of each ofsaid brackets lying in a common plane, and mea-ns for securing togethersaid contacting Walls.

f2. In combination With a column provided with a pair of diametral slotseX- tending a-t right angles to one another, a column cap comprising apair of three Walled brackets formed from structural iron, one Wall ofeach of said brackets being disposed in contacting relation Within oneor said slots, a second Wall of each of said brackets being disposedWithin another of said slots, the third Wall ol each of said bracketslying in a common plane.

3. In combination With a column having a plurality of radially extendingslots in its end, a column cap comprising a plurality of like brackets,each having three Walls, two of said Walls being vertically disposed,and the other being horizontal, and means securing a vertical Wall ofone bracket to a vertical Wall of another, such connected pair of Wallsbeing disposed within one of said radial slots in the column.

4. In combination with a column having a diametral slot and anintersecting radial slot in its end, a column cap comprising a pair ofthree Walled brackets each having a vertical Wall disposed in saidradial slot and in contact with one another, and each having a secondvertical Wall disposed in said diametral slot, said last named Wallsbeing in alignment, and an angle iron having one iange also disposed insaid diametral slot and having its other iiange lying in the plane ofthe third Walls of said brackets.

5. In combination with a column provided with a pair of axial slots inits end, a pair of three Walled brackets, a Wall of each bracket beingdisposed in contacting rela tion within one of said slots and a secondWall of each bracket being disposed in alignment in the other of saidslots, a plate like element also disposed in the latter' of said slotsand secured to the aligned Walls of said brackets, and a T-shaped memberhaving its cross-bar secured to said plate like element and its othermember arranged Within said first named slot.

6. A column cap comprising a plurality of three Walled brackets, eachcomprising a horizontal Wall and two vertical Walls, means for securinga vertical arm of one bracket to the adjacent Wall of another bracket,and a plate contact-ingh With and secured to the horizontal Walls of theseveral brackets.
